Embodiment Construction

[0031] Below, refer to Figure 1 ~ Figure 4 A hybrid vehicle according to an embodiment of the present invention will be described.

[0032] figure 1 It is a block diagram showing a configuration example of the hybrid vehicle 1 . The hybrid car 1 is an example of a vehicle. The hybrid vehicle 1 is driven by an engine (internal combustion engine) 10 and / or an electric motor 13 via a transmission device of a semi-automatic transmission, so that regenerative power generation can be performed by the electric motor 13 during deceleration. At this time, the electric motor 13 can generate a braking force like an engine brake of the engine 10 by the regenerative torque generated by the regenerative power generation of the electric motor 13 . In addition, the so-called "semi-automatic transmission" refers to a transmission (transmission) that has the same configuration as a manual transmission but can automatically perform a shifting operation.

Abstract

The present invention suppresses a battery temperature increase while suppressing a decrease in battery SOC. The present invention has: a temperature sensor (20) that detects the temperature of the battery (15); and a hybrid ECU (18) that, when the temperature sensor (20) has detected a battery (15) temperature that is at least a predetermined temperature or that exceeds the predetermined temperature, controls in a manner so that an engine (10) and an electric motor (13) are connected during regenerative power generation during deceleration. The hybrid ECU (18) sets the predetermined temperature in accordance with the gear stage number during hybrid automobile (1) deceleration.

Description

technical field [0001] The present invention relates to a regeneration control device, a hybrid vehicle, a regeneration control method, and a program. Background technique [0002] A hybrid vehicle is provided with an engine and an electric motor, and can run with the engine or the electric motor, or can run with the cooperation of the engine and the electric motor. Here, when the hybrid vehicle decelerates, the motor is rotated by the rotational force of the wheels, so that the motor can function as a generator and charge the storage battery of the hybrid vehicle (this is referred to as "regenerative power generation"). [0003] When the electric motor performs regenerative power generation in this way, regenerative torque is generated in the electric motor in proportion to the regenerative electric power of the electric motor. This regenerative torque acts as a braking force when the hybrid vehicle decelerates (for example, refer to Patent Document 1). At this time, in o...
